Image description: a screenshot from the Wikipedia page for the Doctor Who TV series, with a user-added caption that reads "Preserve the media you can before it's gone forever." The Wikipedia article reads, "No 1960s episodes exist on their original videotapes (all surviving prints being film transfers), though some were transferred to film for editing before transmission and exist in their broadcast form. [88] Some episodes have been returned to the BBC from the archives of other countries that bought prints for broadcast or by private individuals who acquired them by various means. Early colour videotape recordings made off-air by fans have also been retrieved, as well as excerpts filmed from the television screen onto 8 mm cine film and clips that were shown on other programmes. Audio versions of all lost episodes exist from home viewers who made tape recordings of the show. Short clips from every story with the exception of Marco Polo (1964), "Mission to the Unknown" (1965) and The Massacre (1966) also exist."
Sorry to be that guy but if the tapes were never preserved it's probably because nobody cared...
The BBC stupidly recycled the tapes because they didn't give much credence at the time to how important their archive would become.
This was a common practice, especially during a certain decade but I forget which. Old tapes were erased to be used again. No thought was given to preserving what was being wiped.
It was a cost-cutting measure to save money on tapes by reusing the old ones.
People absolutely do care. These lost media include the origins of shows that are still relevant today. But backups weren't exactly treated with much care until relatively recently.
I highly doubt it would have cost much to preserve a few of the original tapes.
Yeah that's kinda my point
You got that right.
